In order to help you, we need to know a lot of information. Make sure to include answers to at least the following questions in your initial post.

- what OS (Windows Xp/Vista, Mac etc.) are you running?- what FlightGear version do you use?- what graphics card do you have?- does the problem occur with any aircraft, at any airport?- is there any output printed to the console (black window)?- copy&paste your commandline (tick the "Show commandline box on the last page of FGRun or the "Others" section on the Mac launcher).- please upload a screenshot of the problem.

If you experience FlightGear crashes, please report a bug using the issue tracker (can be also used for feature requests).To run FlightGear on old computers with bad OpenGL support, please take a look at this wiki article. If you are seeing corrupted/broken textures, please see this article.

Note: If you did not get a reponse, even after 7 days, you may want to check out the FlightGear mailing lists to ask your question there.

Now FG doesn't even start, I tried different aircrafts and locations but it always stops loading in loading scenery and it shows on the right-bottom corner the framerate counter saying 0 FPS .Here's my console:

C:/Users/.../AppData/Roaming/flightgear.org/autosave.xmlAny property that has userarchive="y" set (eg. in preferences.xml, or -set.xml) will be saved on quiting. Do note that closing FG with the Windows X does not save anything. Only Esc or File > Quit do

EDIT: Looks like models are also affected. The terminals seem to miss quite some faces...

As I said, same output with shader enabled and with shader disabled. It also seems like I'm the only one having this problem, so probably my graphics card does not support the shader.

EDIT: I tried to disable all the other shaders and let only the generic shader on, but my FG keeps crashing when I move the sliders to the left.
